Abstract: | The Amplatz Thrombectomy Device (ATD) is a percutaneous, rotational thrombectomy catheter, capable of recirculating and homogenizing
the thrombus in order to obtain mechanical clot dissolution. The authors present their experience with mechanical thrombectomy
with the ATD in eight cases of ilio-caval thrombosis. Under temporary caval filter protection, the ATD was introduced through
the right transjugular approach (in one patient this was used in combination with the right femoral approach) and activated
for a time ranging from 90 to 180 s. Complete clearing of thrombotic material in the treated venous segments was achieved
in six cases (75 %), partial success was obtained in one case (12.5 %) and failure occurred in one patient (12.5 %). One patient
developed a recurrence of venous iliac thrombosis 1 week after the procedure and postphlebitic syndrome 6 months after the
first episode of deep venous thrombosis, and one patient died from acute myocardial infarction, unrelated to thrombectomy
session, after 3 days. A negative clinical and radiological follow-up at 3, 6, 12 and 24 months was obtained in the remaining
six patients. If a fresh free-floating ilio-caval clot must be removed immediately, the ATD can be effective under temporary
filter protection.
